Sorry, I meant utf-fragment-on-decoding, which decodes Cyrillic and
Greek into ISO 8859.  (I always get confused and lost in the maze of
those twisted *-on-decoding passages, all alike.)

Right, but what about Cyrillic and Greek?  The merits and demerits of
depending on utf-fragment-on-decoding are not clear when the Lisp
reader is involved.
